Dyson-Schwinger equations and SYM in Landau gauge
Axel Maas, Stefan Zitz
Super Yang-Mills theory is a highly constrained theory, and therefore a valuable tool to test the understanding of less constrained Yang-Mills theories. Our aim is to…
Orbits in the T Tauri triple system observed with SPHERE
R. Köhler, M. Kasper, T. M. Herbst +2
We present new astrometric measurements of the components in the T Tauri system, and derive new orbits and masses. T Tauri was observed during the science verification time of the…
Superconductivity in metastable phases of phosphorus-hydride compounds under high pressure
José A. Flores-Livas, Maximilian Amsler, Christoph Heil +6
Hydrogen-rich compounds have been extensively studied both theoretically and experimentally in the quest for novel high-temperature superconductors. Reports on sulfur-hydride attai…
On the effect of time-dependent inhomogeneous magnetic fields in electron-positron pair production
Christian Kohlfürst, Reinhard Alkofer
Electron-positron pair production in space- and time-dependent electromagnetic fields is investigated. Especially, the influence of a time-dependent, inhomogeneous magnetic field o…
DR Tau: Temporal variability of the brightness distribution in the potential planet-forming region
Robert Brunngräber, Sebastian Wolf, Thorsten Ratzka +1
We investigate the variability of the brightness distribution and the changing density structure of the protoplanetary disk around DR Tau, a classical T Tauri star. DR Tau is known…
Smoothness of moments of the solutions of discrete coagulation equations with diffusion
Maxime Breden, Laurent Desvillettes, Klemens Fellner
In this paper, we establish smoothness of moments of the solutions of discrete coagulation-diffusion systems. As key assumptions, we suppose that the coagulation coefficients grow…
Generalized Goncarov polynomials
Rudolph Lorentz, Salvatore Tringali, Catherine H. Yan
We introduce the sequence of generalized Gončarov polynomials, which is a basis for the solutions to the Gončarov interpolation problem with respect to a delta operator. Explicitly…
On the number of distinct prime factors of a sum of super-powers
Paolo Leonetti, Salvatore Tringali
Given , let be, for and , some fixed integers, and define, for every , $s_n := \sum_{i=1}^k \pro…
TRIQS/DFTTools: A TRIQS application for ab initio calculations of correlated materials
Markus Aichhorn, Leonid Pourovskii, Priyanka Seth +9
We present the TRIQS/DFTTools package, an application based on the TRIQS library that connects this toolbox to realistic materials calculations based on density functional theory (…
More on the properties of the first Gribov region in Landau gauge
Axel Maas
Complete gauge-fixing beyond perturbation theory in non-Abelian gauge theories is a non-trivial problem. This is particularly evident in covariant gauges, where the Gribov-Singer a…
The VISTA Carina Nebula Survey II. Spatial distribution of the infrared-excess-selected young stellar population
Peter Zeidler, Thomas Preibisch, Thorsten Ratzka +2
We performed a deep wide-field (6.76 deg^2) near-infrared survey with the VISTA telescope that covers the entire extent of the Carina nebula complex (CNC). The point-source catalog…
Poincare covariant pseudoscalar and scalar meson spectroscopy in Wigner-Weyl phase
Thomas Hilger
The coupled quark Dyson-Schwinger and meson Bethe-Salpeter equations in rainbow-ladder truncation for spin-0 mesons are solved in Wigner-Weyl phase in the chiral limit and beyond,…
A network of filaments detected by Herschel in the Serpens Core: A laboratory to test simulations of low-mass star formation
V. Roccatagliata, J. E. Dale, T. Ratzka +6
Filaments represent a key structure during the early stages of the star formation process. Simulations show filamentary structure commonly formed before and during the formation of…
Chiral symmetry aspects in the open charm sector
Thomas Buchheim, Thomas Hilger, Burkhard Kampfer
QCD sum rules serve as tools to investigate changing hadronic properties in a hot and/or dense nuclear medium. The role of chiral symmetry breaking and restoration effects in a med…
Towards the spectrum of a GUT from gauge invariance
Pascal Törek, Axel Maas
The description of electroweak physics using perturbation theory is highly successful. Though not obvious, this is due to a subtle field-theoretical effect, the Fröhlich-Morchio-St…
Influence of bonding on superconductivity in high-pressure hydrides
Christoph Heil, Lilia Boeri
The recent reports on high-temperature superconductivity above 190 K in hydrogen sulfide at 200 GPa pressure, exceeding all previously discovered superconductors, has greatly invig…
Orbital tomography of hybridized and dispersing molecular overlayers
Thomas Ules, Daniel Lüftner, Eva Maria Reinisch +3
With angle resolved photoemission experiments and \emph{ab-initio} electronic structure calculations, the pentacene monolayers on Ag(110) and Cu(110) are compared and contrasted al…
Experimental and theoretical electronic structure of quinacridone
Daniel Lüftner, Sivan Refaely-Abramson, Michael Pachler +4
The energy positions of frontier orbitals in organic electronic materials are often studied experimentally by (inverse) photoemission spectroscopy and theoretically within density…
Products of atoms in Krull monoids
Yushuang Fan, Qinghai Zhong
Let be a Krull monoid with finite class group such that every class contains a prime divisor. For , let denote the set of all $m\in \mathb…
Light-quarkonium spectra and orbital-angular-momentum decomposition in a Bethe-Salpeter-equation approach
T. Hilger, M. Gomez-Rocha, A. Krassnigg
We investigate the light quarkonium spectrum using a covariant Dyson-Schwinger-Bethe-Salpeter-equation approach to QCD. We discuss splittings among as well as orbital angular momen…
Factorizations of Elements in Noncommutative Rings: A Survey
Daniel Smertnig
We survey results on factorizations of non zero-divisors into atoms (irreducible elements) in noncommutative rings. The point of view in this survey is motivated by the commutative…
Improvements on coronal hole detection in SDO/AIA images using supervised classification
Martin A. Reiss, Stefan J. Hofmeister, Ruben De Visscher +5
We demonstrate the use of machine learning algorithms in combination with segmentation techniques in order to distinguish coronal holes and filaments in SDO/AIA EUV images of the S…
A Characterization of class groups via sets of lengths {II}
Alfred Geroldinger, Qinghai Zhong
Let be a Krull monoid with finite class group and suppose that every class contains a prime divisor. If an element has a factorization $a=u_1 \cdot \ldots \cdot u…
Current characteristics of a one-dimensional Hubbard chain: The role of correlation and dissipation
Jakob Neumayer, Enrico Arrigoni, Markus Aichhorn +1
We study the electronic transport in an infinite one-dimensional Hubbard chain, driven by a homogeneous electric field. The physical chain is coupled to fermion bath chains, in ord…
